Problems solved by technology

Since the list of trusted IP addresses needs to be configured in advance, the applicability of this method is poor
However, when an enterprise uses CDN acceleration, the list of trusted IP addresses changes so frequently that this method cannot be used at all.

Abstract

The invention discloses a method for preventing original address spoofing attacks, a device, a server and a storage medium. The method includes: when a user terminal initiates an access through a browser, automatically extracting a list of IP addresses that initiate the access according to the access ; Judging whether the IP address in the IP address list is a trusted IP address, wherein the IP addresses that are judged to be the LAN IP address and the user's own IP address in the IP address list are all determined as trusted IP addresses. The remaining IP addresses in the address list are judged by IP address reputation and IP address geographic location to determine whether they are trusted IP addresses, and the determined trusted IP addresses form a trusted IP address list; when the source IP address of the http request is the described When the IP address in the trusted IP address list is selected, the XFF field is extracted, and whether the XFF field is legal is detected. The method automatically processes the traffic, automatically identifies the trusted IP address list, and prevents original address spoofing attacks.

Description

technical field [0001] The invention relates to the Internet, in particular to a method, device, server and storage medium for preventing original address spoofing attacks. Background technique [0002] In the field of the Internet, when a user accesses the WEB server through a browser, when accessing the WEB server through an HTTP (Hyper TextTransfer Protocol) proxy or a load balancing server, an XFF field (also known as XFF Header), where XFF is the abbreviation of X-Forwarded-For, which is used to identify the most original IP (Internet Protocol) address of the client connecting to the Web server through HTTP proxy or load balancing. In layman's terms, it is the IP address of the browser accessing the website. [0003] If there is no XFF or another similar technology, all connections through the proxy server will only display the IP address of the proxy server, rather than the original IP address initiated by the connection. Such a proxy server actually acts as an anonym...
